您好我正在使用 XUpload 在我的应用程序中上传照片，但是当它上传到相应的文件夹时，它无法保存到我的数据库中。下面是添加照片的代码。模型是旋转木马。请帮忙。谢谢。

public function afterSave() 
{
$this->addImages();
parent::afterSave();
}

public function addImages() 
{
//If we have pending images
if( Yii::app( )->user->hasState('carouselphoto') ) {
    $userImages = Yii::app( )->user->getState('carouselphoto');
    //Resolve the final path for our images
    $path = Yii::app( )->getBasePath( )."/../images/uploads/{$this->id}/";
    //Create the folder and give permissions if it doesnt exists
    if( !is_dir( $path ) ) {
        mkdir( $path );
        chmod( $path, 0777 );
    }

    //Now lets create the corresponding models and move the files
    foreach( $userImages as $image ) {
        if( is_file( $image["path"] ) ) {
            if( rename( $image["path"], $path.$image["filename"] ) ) {
                chmod( $path.$image["filename"], 0777 );
                $img = new Carousel();
                $img->size = $image["size"];
                $img->mime = $image["mime"];
                $img->name = $image["name"];
                $img->photo_name = "/images/uploads/{$this->id}/".$image["filename"];
                $img->id = $this->id;
                if( !$img->save( ) ) {
                    //Its always good to log something
                    Yii::log( "Could not save Image:\n".CVarDumper::dumpAsString( 
                        $img->getErrors( ) ), CLogger::LEVEL_ERROR );
                    //this exception will rollback the transaction
                    throw new Exception( 'Could not save Image');
                }
            }
        } else {
            //You can also throw an execption here to rollback the transaction
            Yii::log( $image["path"]." is not a file", CLogger::LEVEL_WARNING );
        }
    }
    //Clear the user's session
    Yii::app( )->user->setState( 'carouselphoto', null );
}
}

谢谢乔米勒。这是我的访问规则代码片段。但是，没有任何错误

{
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('photo_name', 'required'),
        array('gallery_id', 'numerical', 'integerOnly'=>true),
        array('photo_name, alt', 'length', 'max'=>256),
        // The following rule is used by search().
        // @todo Please remove those attributes that should not be searched.
        array('id, photo_name, gallery_id, alt', 'safe', 'on'=>'search'),
        array('photo_name', 'file', 'types' => 'jpg,jpeg,gif,png'),
    );
}

这是设置的位置（actionUpload）

//Now we need to save this path to the user's session
            if( Yii::app( )->user->hasState('carouselphoto') ) {
                $userImages = Yii::app()->user->getState('carouselphoto');
            } else {
                $userImages = array();
            }
             $userImages[] = array(
                "path" => $path.$filename,
                //the same file or a thumb version that you generated
                //"thumb" => $path.$filename,
                "filename" => $filename,
                'size' => $model->size,
                'mime' => $model->mime_type,
                'name' => $model->name,
            );
            Yii::app( )->user->setState( 'carouselphoto', $userImages );

我有同样的问题，你不应该做的一件事是调用 if( !$img->save( ) ) @Joe Miller 说你有递归。

我尝试在分配后打印 $img->name = $image['name'] 并且它确实有效。

但是这种变化并没有反映在数据库字段上......不知道为什么。

我打算这样尝试：

if(Yii::app()->user->hasState('xuploadFiles' )) {   
$this->addImages();
return true;
}parent::afterSave();

因为可能返回 parent::afterSave(); 始终返回 false，因此它不会保存该字段。我不知道..我需要先检查一下。

解决了

对我来说这样工作： $this->saveAttributes(array('image_url'));

你应该试试它是否适合你。$this->saveAttributes(array('size,mime, name, photo_name, id '));
